Specification of Letters Patent. Patented Mar. 1911.

Application filed June 8, 1906. Serial No. 320,736.

To all, whom it may concern:

Be it known that I, EDOUARD MARIE QUEL- LENNE'C, a citizen of the Re ublic of France, and residing in Paris, France, engineer, have-invented a .Rotary Automobile Plowing and Harrowing Machine, of which the following is a speclfication.

The present invention-relates to a rotary automobile plowing and harrowing machine, serving to break up the ground by digging, shoveling or cutting, and consequently to. replace both the ordinary plow and harrow.

This machine is based upon the principle of the rotary digging, shovelin or cutting obtained by means of multiple picks, shovels or saws mounted upon one and the same shaft perpendicular to the axis of translation of the machine and to which a movement of rotation is imparted by means of a mechanical motor.

An example of this machine is represented in the accompanying drawings, in which:-

Figure 1 represents a' longitudinal elevation of the machine provided with the digging tool. Fig. 2- is a corresponding plan View. Figs. 3 and 4 illustrate the arrangement of the shoveling tool in elevation and in plan respectively. Figs. 5 and .6 show the arrangement of the cutting tool in elevation and in planrespectively. Fig. 7 is a cross section of the lifting pin mechanism for the jib. Figs. 8, 9 and 10 are detail views of the cutting tooL' The machine is composed broadly (Figs.

1 and 2). of a frame on four wheels and of a rotary digging, shoveling orcutting tool arranged at the rear of the frame. The traveling movement of the machine, and the movement of rotation of the tool are produced by means of any appropriate motor, such as a gasolene, spirit, alcohol, steam, electric or other motor mounted upon the frame. The transmission of the movement to the driving wheels R R of the machine with change of speed for different conditions of work and of transportation has not been shown in order to simplify the drawmg.

The method of transmitting movement to the tools shown in the drawing is only given 1 by way of example; it is likewise by Way of illustration that this drawing shows a twoground, springs c,

- upon the arms of the necessary additional pressure.

speed gear because if the same apparatus is intended to work on land of difierent composition, the transmission, gear should be adapted to produce as many different speeds as'necessary. As shown in the drawing, the variable speed is obtained by means of the clutch 11 mounted on a feather 12 driven bythe motor G and adapted to be moved into engagement with either of the free pinions .13 or 14 which are of difl'erent size and mesh with corresponding pinions l5 -and 16 on the spindle 17. The spindle b is latter by means of the driven from the chain 18.

The tool, whether it be a pick, shovel or cutter, comprises a shaft A B upon which there are mounted side by side disks each of which. carries a certain number of picks (Figs. 1 and 2) shovels (Figs. 3 and 4;) 'or cutting elements (Figs. 5 number, form and dimension of the picks, shovels or cutting elements, their projection from the shaft and them upon this shaft, may vary according to the nature and composition of the land, the depth to which it is to be tilled, and generally speaking in accordance with the local conditions to be complied with. The picks, shovels and the cutting elements are curved in such a manner as to merely owing to the fact of the rotation of the shaft A B.. During the operation, the picks, shovels or saw cutting elements owing which they seize the ground, assist the forward movement of the machine. The manner in which the tool works also produces on the shaft and 6). The

penetratethe groundthe method of mounting to their curved form, and the manner in an intimate mixing of the manure with the ground.

The picking, shoveling or cutting tool may be connected to the frame in any appropriate manner, but so that it may be raised and lowered at will. In the drawing the connection is effected by means of a ladder frame or jib with two arms a, a rotatably mounted upon a shaft 6 fixed to the framework. If the weight of the jib and of the tool'is not su-flicient to keep the picks, shovels, or cutting elements well in engagementwith the 0 bearing on the one hand upon the frame, and on the other hand jib, will supply the is raised or lowered by means of screw pins P to which its arms a. a are connected by bolts Working within terminal eyes in the ins. The pins pass through screw threaded earings d rotatably mounted in the frame. On one of these bearings is secured a gear wheel 9 which meshes with the pinion g on the spindle carrying the hand wheel M. Each of the bearings is provided also with a cogwheel f, f over which the chain 6 passes thus securing their synchronous rotation. It is thus apparentthat by actuating the hand wheel M the jib carrying the tool may be raised or lowered to secure any desired depth of tillage or may be carried entirely above the ground during the transportation of the machine. There is an eye joint betweenthe jib and the screw P which permits a certain play between the parts to accommodate obstacles opposing great resist.- ance to' the rotation and advance of the tool. Springs 0, 0 may be arranged it necessary to deaden the shocks produced by this rising of the tool. i

For the purpose of detaching the earth it' it remains adhering to the picks after they leave the ground, a cleaning device composed of a series of knives mounted upon one and.

the same bar T T is employed; these knives engage between the picks during their movement of rotation in such a manner as to loosen the earth automatically; these knives are able to rise partially in order to avoid to which it is to gation the risk of breakage 1n case the eifort to be overcome should be too great. For this purpose they may be pivotally mounted on the bar T as shown in Fig. 1, and provided with springs t to return them to position after deflection.

In order that the soil may lie quite uniformly after the passage of the apparatus, a rake V V is loosely secured by means of arms 2', i, to the ends of thejib arms a,

The cutting tool (Figs. 5 and 6) is composed of a shaft A B on which there are mounted side by side circular plates provided with two teeth upon their edge, and upon their faces. The teeth bothupon the edge and alternate external teeth and pro ect sulficiently for producing the complete disaggreof the ground between the two adjacentplates; they are curved in order to bite the ground and assist the forward movement. Further, the number, form and dimensions of the teeth, and also their projection may vary and the disposition of the ground, the depth be worked and generally plurality of suitably upon the faces of the plate are in accordance with the nature eeaoao speaking in accordance with the local conditions.

This tool is specially adapted for treating the hardest and driest land. It roots up the stubble, roots and grass, and breaks up and pulverizes the ground.

The cutting tool is connected to the frame and driven by the motor in the same manner as the digging or shoveling tool. In the drawing, the chain for the transmission of movement to the tool is shown in the middle, but it might equally well be placed at the extremity. V

-In order to prevent the earth from being projected, there may be arranged at the rear extremity of the machine parallel with the shaft of the cutting tool a screen 3' which serves to stop theearth projected by the teeth of the saw.

Although I have shown and described a gasolene or the like motor mounted upon the frame for the purpose of imparting a' traveling movement to the machine, I do not desire to limit my invention to this-motive means, and it should be understood that any appropriate means or mechanicaltraction may be employed in order to impart a traveling motion to the vehicle.

What I claim and desire to secure by Let ters Patent of the United States-is:--

1. In a machine of the character described, a rotary tillingtool comprising a ormed disks, 2. jib carryin the same, in combination with an upward y angled extension of said jib beyond said tool and a screen arranged behind the tool and carried by said extension, substantially as described.

2. In a machine of the character described, a. rotary tilling tool, a flexibly mounted jib carrying the same, said jib comprising a plurality of arms supporting the shaft of said tool, in combination wlth a plurality of threaded eye bars extending down to said arms of the jib, means in connection with the latter for engaging with lost motion the eyes of said eye bars and means for screwing said eye bars up and down whereby the position of said jib may be controlled.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
